Crossbite

The crossbite describes a reverse overbite of the teeth. The upper dental arch is usually bigger and broader than the lower so that both the front and posterior teeth overlap the lower teeth in the bite. However, in the case of crossbite, the lower teeth actually overlap the upper teeth. A frontal crossbite can sometimes be a sign of a protruded lower jaw, whereas a lateral crossbite is usually a sign of an upper jaw that is too narrow. Crossbites are considered to be in need of treatment according to the current KIG rules and trigger entitlement to benefits from the statutory health insurance for orthodontic treatment.
